BCILAB Parameters
Hi everyone!
I am currently an undergraduate student at UC Davis. I am apart of a research team using BCILAB for a project. I just have a question on specific parameters that we are not clear on. For example, we are unclear what "Sampling rate after resampling" means. The default value for that is 100 and I am aware that it is a rate in Hz but what exactly is is sampling and what does it mean by resampling? Also, what does "Number of CSP patterns(times two)" stand for? These are the two parameters our team is struggling to figure out what they actually. Any help would be appreciated and thank you in advance!

Resampling is sometimes done to reduce a high sample rate (such as 1000 or 500 hz) down to rate that requires less computational resources. As long as your final sample rate is above the Nyquist limit for your data (2 or better 3 or more samples per waveform), then you are ok.
But the OpenBCI sample rates are low enough (250 or 125 sps, or 200 for Ganglion), that no resampling is needed.
